CAN-HEADING' MACHINE.

Patented Jan. 4, 1916.

Application filed September 29, 1913. Serial No. 792,296.-

To all whom it may concern:

Be it known that I, JULIUS BRENZINGER, a citizen of the United States, residing at Mount Vernon, in the county of -Westchester and State of New York, have invented certain new and useful Improvements in Can-Heading Machines, of which the following is a specification.

This invention relates to machines forhermetically sealing the tops or covers to the body'portions of sheet metal containers, commonly known as tin cans, by what is known as the double seaming process, with more particular reference to mechanism'for facilitating the delivery of the assembled can parts in proper adjustment to the seaming mechanism proper and posltioning the same therein.

In a co-pending application, filed by me September 29, 1913, Serial No. 792,291, I

have shown and described a machine in which the function's above referred to are performed automatically, and the present invention contemplates a simpler form of machine, seaming mechanism manually, the invention residing more specifically in a device for facilitating the feeding operations and insuring proper positioning of the assembled and suitably supported can parts in the seaming mechanism.

As suggested above, the principal object of the present invention is that of facilitating the operation and thereby increasing the capacity of a machine in which the assembled can parts are designed to be manu the provision of adjuncts which not only insure more nearly perfect adjustment of the assembled parts in the seaming mechanism, but which simplify the usual manual operations and reduce the number thereof. Incidental to the above, I have in View a double seaming ma chine which is not only simple in construc tion and operation, durable and dependable, but one which, although requiring manual manipulation of the cans in delivering the same to and ejecting them from the seaming mechanism, may be operated at great speed and be at all times under perfect control of a comparatively unskilled operator in charge. Y

My invention will be readily understood central in which the can parts are fed to the.

member which by reference to the accompanying drawings, forming a part of this specification, in which:

Figure 1 is a side elevation of a can heading machine embodying my invention; Fig. 2 is a horizontal section taken substantially on the line 22 of Fig. 1; Fig. '3 is a horizontal section taken substantially on the line 33 of Fig. 1; Fig. a is a central sectional elevation, on an enlarged scale, of the mechanism for feeding the assembled can parts to the seaming mechanism and adjusting the same therein; Fig. 5 is a view similar: to Fig. 4 with the parts in a different position of adjustment, a part of the feeding mechanism being omitted; Fig. 6 is a horiaontal section taken substantially on the line 66 of Fig. 5; Fig. 7 is an enlarged sectional elevation of the seaming head and its actuating mechanism; Fig. 8 is a section taken substantially on the line 88 of Fig. 7, and Fig. 9 is a side elevation of the collar for raising the platform-sup porting shaft, as hereinafter described.

eferring now to the drawings in detail, number 11 designates the main frame of the machine, which is preferably provided with the heavy supporting base 12'. In the upper portion of the frame 12 is journaled the main driving shaft 13, provided with the fastand loose pulleys 14 and 15 for connec tion in'the usual manner with any suitable and convenient source of power. In arms which are provided in'the upper portion of the frame 11, is journaled the vertical shaft 16, driven from the shaft 13 by means of intermeshed bevel gears 17 and 18. A shaft 19 is also mounted in these arms, this shaft being non-rotatable, but having a limited vertical sliding movement in said arms; Revoluble upon the shaft 19 is a sleeve 20 carrying a gear 21 in mesh with a gear 22 on the shaft 16. The gear 21 is integral with or secured to a toothed collar 23, which provides an upper clutch member with which is adapted to cooperate a correspondingly toothed collar 24 providing a lower clutch includes the grooved tion 29 and the tat-able on the shaft 19, and is connected "ith said sleeve by means of a feather 7 3or has other suitable connection whereby said p0rcam 30. This collar 24; is mounted on the upper end of a sleeve 68, r0"- of velocities being preferably sleeve is rotated by rotation of said collar and yet the latter has a limited vertical sliding movement on said sleeve. The sleeve 68 terminates at its lower end in an eccentric head 69, and revoluble upon the con centric upper portion of said sleeve 68 is another sleeve 70, fixed upon the upper end of which is the gear 25 which forms part of a collar which includes the cam 43, said ear 25 being in mesh with the gear 26 on the shaft 16.

The two cams 30 and 43 are normally in what may be termed an interfitting condition, each, raised cam surface extending through an arc of approximately 180 and being located, when the collar 24 is in its depressed or lowermost position, within the corresponding depressed surface of the other cam member.

At the lower end of the sleeve is provided a flange 71 which carries the seaming head 27, preferably through the medium of the threaded ring 72 which forms an interior annular groove into which said flange projects... This flange is provided with a radially-disposed slot 74 into which projects a pin on the upper face of the seaming-head 27 whereby'the latter is rotated by the former. Furthermore, the peripheral diameter of said flange being less than the diameter of said annular groove, it will be apparent that .said seaming-head will have a certain freedom of lateral movement on its support, this movement being limited, first, by rotation of the eccentric head 69, upon which said seaming-head is journaled, and, second,'by the pin 75 in the slot 74. This construction is similar to that shown and described in my co-pending application aforesaid, and the manner in which a slight variation in the velocities of the sleeves 68 and 70 will serve to regularly vary the axis of rotation of the seaming head 27, and thereby vary the orbits of revolution of the seaming rollers thereon (only one roller 28 being shown in the drawings) to periodically move said rollers in succession to and from cooperative positional re lation to the chuck 31, is shown'and described in detail in another co-pending plication, filed July 5, 1910, Serial NE). 570,343.

For the purpose above briefly set forth, the gears 21 and 25 are so proportioned with relation to the gears 22 and 26, respectively, that the gear 25 is driven at a slightly greater velocity than the gear 21, the ratio that of 15: 14. However, when the collarwhioh includes the cam 30 is in its depressed or lowermost position, with the cams 30 and 43 in what lgfhave termed their interfitting' relation, it will be apparent that the sleeve 68 and the sleeve 70 will both be rotated in unison from the gear 26 in mesh with the gear 25.

Under such conditions, the eccentric head- 69 and the seaming head 27 will obviously rotate in unison and the seaming rollers be revolved in substantially circular orbits which will be at a maximum distance from the chuck 31 when the cams 30 and 43 are so positioned as to come into engagement when the eccentricity of the head 69 is on the same side of the chuck 31 as that upon which the seaming rollers on the head 27 are located. However, when the collar which includes the clutch member 24 and the cam 30 is raised to free the cams 30 and 43 from each other, and at the same time bring the clutch members 23 and 24 into engagement, 1t Wlll be apparent that while such condition continues the sleeve 7 O which carries the seaming-head will be rotated from the gear be subsequently withdrawn therefrom in a similar manner, as explained.

A vertical rod or shaft 32 is mounted for limited reciprocating movement in suitable slide bearings in the arm 33 of the frame 11, and carries at its upper end a disk 34, which may be termed a platform, and which is adapted to receive the can body 35 and be raised to support the latter against a chuck 31 for the seaming operation. The upper face of this platform 34 is normally in the same horizontal plane as the upper face of the table 36, and with said rod or shaft 32 is positioned under the chuck 31, preferably projecting into a recess in said table, so that can bodies may slide smoothly from tabie to platform. 4

J ournaled in suitable bearings at the end of the arm 33. of the frame 11 is the shaft 37 carrying at its upper end a circular plate or disk to which is secured a substantially star-shaped casting 39, this member having four semicircular recesses or pockets of suitable size and shape to receive the can bodies. This member 39-is further provided at each recess with a split post 40 which carries a curved strip 42 of spring metal having flaring ends which may be sprung apart by the insertion therebetween of a can body and which embrace said body to retain the same in the recess or pocket by yielding forces which, while suflicient to insure proper lateral positioning of said body under the chuck 31, permit of movement of said body upwardly to said chuck and downwardly therefrom under the action of gravity, and also permit of ready removal-of said body after the seaming operation.

Guide posts 41, 41 are provided to retain the ends of the spring strip in proper position.

Loosely mounted on the shaft 37 is a collar 45, supported upon the fixed collar 76 which also serves to support said shaft 37 in its bearings at the end of the arm 33. This loose collar 45 is provided with a lug or projection 46 carrying the pivot 47 upon which are fulcrumed the arms 49 and 50 of a yoked hand lever 48. The shorter arm 49 has no function other than that of providing a stable fulcrum, the arm 50 being longer and carrying at its end a roller 51.- It will be seen that this lever is operable horizontally about theshaft 37 as a fulcrum and also vertically upon the pivot 47 as a fulcrum.

that the arm 50 thereof with its roller 51' has been brought underneath the widened portion of the flange 53 on the collar 52, and is then depressed, the shaft 32 will be raised to elevate the platform 34.

Fixed upon the shaft 32 is the collar 54, connected with loose collar 55 through the interposition of rubber or other yielding buffers 56, whereby said collar 55 will be raised and lowered with said shaft 32 under yielding forces. A link 57 connects the loose collar 55 with the end of the lever 58, fulcrumed at 59 in the frame of the machine. The other end of the lever 58 is connected with the corresponding end of lever 60 by means of the rod 61, said lever 60 being fulcrumed at 62 and carrying at its other end the connecting rod or link 63, the other end of which may be provided with a suitable roller adapted to travel in a groove of the collar "29, or, as shown in the drawings, and as I consider preferable, the end of the link 63 may be attached to a strap 77 in said gro0veeither being a well-known form of connection by means of which said collar may -be raised and lowered independent of rotation thereof.

From the above description it Will be apparent that when a can body 35 is positioned upon the platform 34, with its can top or cover properly adjusted for the seaming operation, the handle of the lever 48 may be depressed to raise the assembled can parts to the point where the top or cover comes into engagement with the chuck 31 which, as is well known, fits within a central depression in said cover and thus servesnot .son in an interfitting only to retain the can top is place but also operates in a well known manner to support the edges of the same against the forces of the seaming operation.

The chuck 31 may be permanently held by the shaft 19 in such relative vertical position that the working peripheral edge thereof is constantly in the same horizontal plane as the working peripheral edges of the seaming rollers. However, on account of the fact that it has been found desirable to yieldingly engage the can top before it becomes rigidly clamped against the flanged body portion of the can, particularly when the container has been over-filled for the purpose of bringing the contents thereof up to the desired weight, in order to minimize the chances of displacement of the top or cover as the assembled parts are being brought into a rigidly clamped condition, it has been found preferable in most cases to so mount the shaft 19 as to make the same vertically reciprocable through a slight distance, in order that the chuck 31 may be normally located sllghtly below the plane of the seaming rollers, so that it is first yieldingly engaged by the r1sing can top and raised therewith and with the shaft 19 to proper vertical position for the seaming operation. After the seamed container has been removed, the

chuck may be returned to its normally depressed position under action of gravity, the welght of the shaft 19 being sufiicient for this purpose. It will be apparent from Fig. 7 that the shaft 19 may be loosely feathered to the various therewith and thus be vertically reciprocable as explained and for the purpose set forth.

It will be apparent, therefore, that when the handle of the lever 48 is depressed, not only will the shaft 32be raised to elevate the assembled can parts to proper position in the seaming mechanism where they are suitably supported against the forces of the seaming operation, but, through operation of the lever 60, the cam members 30 and 43 will .be

separated and the clutch members 23 and 24 be brought into engagement, thus renderlng operations of the seaming mechanism effective through varying the velocities of rotation of the sleeve 68 which carries the eccentric head 69 and the sleeve 70 which carries the seaming-head 27. Now, upon separation of the cam members 30 and 43, which have theretofore been rotating in uni-' relation, the 'velocity of rotation of the upper cam member 30 is at once slightly increased. Therefore, the

' forward end of theraised surfac'e of the of necessity slightly parts which have connection upper cam member will be advanced over the rear end of the raised surface of the lower cam member and the former be supported by the latter in its raised position throughout the entire cycle during which the seaming operation is started and comcan body, even if the arm 50 of the lever 48 is immediately withdrawn from the collar 52. While under ordinary conditions the forces of gravity would doubtless be sufli cient to return the platform 34 to its depressed position and return the cam member 30 to inter-fitting relation to the cam member 43 at the end of each revolution of one cam member relative to the other, I prefer to provide a tension spring 64, interposed between the rod 61-and the frame 11, to augment the forces of gravity for the purposes set forth.

Keyed to the shaft 37 is the disk wheel 65, provided,on its under face with preferably four notches or recesses 44 which areequidistantly spaced apart. Each of these notches 44 is of a size and shape to receive the end of a stud 66 on the lever 48. It will be apparent that with these parts in substantially the positions indicated in Fig. 5,

' the handle of the lever 48 may be raised to cause the stud 66 to enter the recess 44 immediately above the same in the disk 65. The lever 48 may then be moved to the left (Fig. 5) through an arc of 90 degrees, which will obviously have the effect of rotating the shaft 3.7 with the member 39 thereon through a corresponding arc, and at the same time serve to bring the longer arm 50 of said lever underneath the enlarged portion of' the flange 53 on the collar 52, whereupon said lever. 48 may be immediately depressed (as shown inFig. 4) to elevate the can 35 in themanner described. Fig. 2 beinga section on the line 2-2 of Fig. 1, is supposed to show the lever 48 in the depressed position,

with the can body 35, therefore, in a raised position and being subjected to the first stages of the seaming operatlon.

Immediately after the can body 35 has been raised and the seaming operation thereon started, with the various parts now in the positions indicated in Fig. 4, the operator grasps another can body 67 on the table 36, with the top or cover superposed thereon, and forces the same between the ends of the spring strips 42, where it is yieldingly retained in the next succeeding recess or pocket in the member.39, as shown in Fig. 2. At the same time, the handle of the lever 48 may be at once raised, the platform 34 remaining in its elevated position and the can 35 remaining in a properly supported condition, as explained, and said handle then moved in the direction of the arrow (Fig. 2) through an arc of 90 degrees, which bringsthe lug 66 on said lever underneath the notch in the disk wheel on the Side thereof opposite to the side upon which the can 67 is located, whereupon the handle of said lever may be raised to again engage said disk wheel in the manner described. During these operations, the seaming operation on the can 35 will have been completed, and said can been returned with the platform 34 to their original depressed positions, the spring arms 42 still yieldingly retaining the can 35 therebetween. Therefore, as the handle of the lever 48 is again moved to the left from the position indi cated in Fig. 6, the can body 67 will be advanced toward the platform 34 as the now seamed can 35 is being by the same means withdrawn therefrom. At the end of this horizontal stroke of thelever through an are of degrees, it will be apparent that I are held out of coiiperative relation to the chuck 31 in the absence of the operation of raising the assembled parts of a can to be headed and thereby operating the clutch mechanism, as described. The seaming tools, therefore, will be brought into work-engaging positions when, and only .when, the

means for positioning a can body in the seaming mechanism is operated, and will be automatically withdrawn from such positions immediately upon completion of the seaming operation. Furthermore, it will be noted that once the platform 34 is elevated, with a can body .31 thereon, and the clutch mechanism is rendered operative, the means which have served to raise said platform may be withdrawn therefrom, and

still the can body will be properly supported throughout the seaming operation.

Of course the machine just described, be-

ing hand-operated so far as the feeding mechanism is concerned, will obviously not have the capacity of machines 'to which the assembled can p'arts are delivered and the seamed can e ected automatically, such as shown and described in my co-pending application aforesaid. However, automatic feeding and ejecting devices are more complicated and expensive, and the principal purpose of this invention is the provisionof an improved hand-fed machine, the caand newer pacity of which is only limited by the skill of a single operator, and which is so simple in construction as to be in cost Within the reach of smaller packers and other users of these machines, the volume of Whose business would not justify the expense of more complicated and expensive machinery.

Many modifications of my improved can heading machine will doubtless readily suggest themselves to those skilled in the art to a which it appertains, and I therefore do not desire to limit my invention to the specific construction herein shown and described.
